Abstract

This paper describes a simulation model used for examining sinking acceleration of an elevator caused by forklift front wheels get on it. When the front wheels of the forklift get on a freight elevator, vertical vibration of the elevator will be generated with the elasticity of the suspension ropes. As a result, it tends to cause slipping between the rope and the sheave. Therefore, when we design traction ability of the sheave, we need to consider not only the static load in the elevator but also dynamic load. In this research, a simulation model that can express the process of the forklift loading is proposed for estimating sinking acceleration of an elevator.
